Filed Aug. 2, 1939 Patented Jan. 27, 1942 UNITED STATES PATENT. OFFICE I 3 t ,271,286" l .V V I I. I STRAINER STRUCTURE William L. Cheshier, Indianapolis, Ind. I I I Application August 2, issas' rial No. 287,921 I 4 Claims. (01. 210-4 51 This invention relates to a strainer structure wherein the straining element is removable and capable of replacement.

The chief object of this invention-isto provide a strainer structure wherein the straining element may be detachably mounted and in a manner that permits the straining element to.

assume a partially spherical form.

The chief feature of the invention consists in providing two rim members of somewhat similar outline and having peripheries of the same size so that when associated together they have-a vertical clamping engagement whereby a straining element may be clampingly mounted theretween, and substantially surround the upper member. I fl- I Another feature of the invention consists in so detachably mounting the straining element so that the same may be readily removed from the support or clamping construction andrenewed or replaced. v I

An incidental feature of the invention consists in extending portions of the clamping structure so that the same may bear upon the upper periphery or rim of a paint bucket'orthe whichlie parallel to each other and approximately in contact'and which are united at the ends, I4, as shown. The tongue portions'thus formed may be .turned downwardly as indicated at I5 and these prevent lateral movement of the strainerstructure when associated vwitha pailv or bucket. 1 J

Theopposite endsof the portions I2 terminate in elongated arms I 6 which'diverge as they exthe rim structure.

like, and the provision of an elongated handle so that the strainer structure may be .held in tend from the rim ,forming portions I2 andthe same are suitably connected togetheras at IT. Thus, the two portions I6 andportions I'I form a handle. for jtheeri-m structure, previously described, andthis handle structure is; of resilient character in that the two junction portions as indicated at -I6a may be; caused to approach each other to" reduce the peripheral'outline of Herein the rim is shownsubstantially circular in outline.

A second and retaining rim structure is illustrated more particularly in Fig. 2. ltfiincludes the portions I8 and I9; Portions I8 and' I 9 are connected together by upwardly directed somewhat elongated'U-shaped portions 20. The portions I8 in turn at the opposite ends are connected together by the upwardly directed,e1ongated substantially U-shaped portion 2|. The

position with one hand, leaving the other hand free for the painter to strain the the strainer into the paint bucket.

Other objects and features of the invention will be set forth more fully hereinafter.

The full nature of the invention will be understood from the accompanying drawing and the following description and claims.

In the drawing:

Fig. 1 is a top plan view of a strainer structure paint through embodying the invention, the dotted lines therein indicating the bucket or pail upon the rim of which the structure may be supported and into the body of which the strainer portion may be nested.

Fig. 2 is perspective view of one of the rim or clamping elements of the structure support.

Fig. 3 is a similar view of a complementary clamping structur or support.

In the drawing IU indicates a bucket, pail or the like, II indicates a strainer element herein shown in the form of screen wire and downward 1y dished into partially spherical form and having a peripheral portion indicated by the numeral I I a. This peripheral portionlies overthe portions I2 and I2a, as shown in Fig. 1. These portions I2 and I 2a are connected together in the present instance, by the extensions I3 and l3a rim portion shown in Fig. 2 has substantially the same general outline as the rim shown in Fig, 3

andis of the same diameter since both are here-.

in shown substantially circular.

7 A piece of screen wire, sieve cloth, or the like,

of the desired area and outline, is laid'over the .upper rim portion of thestructure shown in Fig.

3. Then the lower rim structure shown in Fig. 2 is laid thereon, the two U-shaped portions 20 lying above theportions I3 and I31; and with said portions nested in the U.-shaped portions 20.

At this stage of the mounting the, U-shaped portion ZI rides above the junctions I 6a of the handle with the rim portion shown in Fig. 3. Thereupon the two portions of the handle I6 arev compressed towards each other so that the junctions lea approach each other and the diameter of the resulting rim is materially reduced. This permits the lower rim shown in Fig. 2to telescope over the upper rim shown in Fig. 3 and for the U-shaped portion 2| to nestingly receive the junction adjacent portions of the handle I6I6.

Upon release of the collapsing pressure on the handle, these portions separate and engage the side walls of the U-shaped portion 2| and thus lock the two rims together. The rim shown in Fig. 2, except'for portions 28 and 2| then lies below the rim portions I2 I2a I2. When this.

locking is effected, it will be noted the straining element almost completely encircles the rim portion of the structure shown in Fig. 3, and thus tension applied to the central portion of the straining element is taken by the upper rim -about which the straining .element substantially envelopes and whatever tension is transmitted to the end portion is absorbed by the lower rim shown in Fig. 2, by reason of its clamping engagement with the upper rim portion.

The resulting structure is one wherein, except for the portions l3-i4--l5, the handle portion iB-ll and the U-shaped portions 20 and 2|, the parts of the structure are covered by the straining element.

In common with other strainers, the resulting structure provides three spaced portions that are adapted to lie on the upper rim of the bucket and thus sustain the strainer in straining position. The painter also upon completion of the straining operation has a handle by which the same may be elevated from the bucket and the strainer may be inverted and tapped so as to discharge the scum et cetera, strained from the paint into a waste receptacle, and the like.

While the invention has been described as applied to a strainer of circular outline and the straining element as of partially spherical form,

it will be perfectly obvious the outline of the strainer may be polygonal or otherwise and that the straining element may be arranged in plane form as distinguished from partial spherical shape. It is sufficient to point out that the chief distinguishing characteristics of the invention, are its simplicity of construction and the ease with which the straining element may be applied to and detached from the rims and further the 'fact that the two rims are of substantially identical outline and of the same size, and the same are arranged in superposed clamping relation instead of telescopic lateral relation.

While the invention has been illustrated and described in great detail in the drawing and foreillustrative and not restrictive in character.

The several modifications described herein as well asothers which will readily suggest themselves to persons skilled in this art, all are considered to be within the broad scope of the invention, reference being had to the appended going description, the same is to be considered as rangement and including one or more outwardly directed projections on the rim, the handle being of dual arm character with arm portions spaced apart and movable towards and away from each other at the rim and a second rim of similar outline and of closed character including a corresponding number of and correspondingly spaced upwardly directed offset portions to nestingly seat the projection, or projections, of the first mentioned rim, and a correspondingly positioned, similarly directed ofiset portion for nesting the handle arm portions when collapsed towards each other, the element being positioned between the rims and clamped therebetween when the rims are clampingly associated together, the rims being substantially identical in size when disassociated, the second mentioned rim lying below the first mentioned rim except for the nesting portions.

2. A strainer structure as defined by claim 1, characterized by the outwardly directed projection, or projections, including downturned ends for retaining said structure upon the upper edge of a container for receiving the strained material.

3. A strainer structure as defined by claim 1, characterized by there being a pair of outwardly directed portions, these being positioned closer to each other than to the adjacent handle arm portions and the second mentioned rim having its first mentioned upwardly directed offset portions positioned closer to each other than to the' second mentioned offset portion of the second mentioned rim.

4. A strainer element support includin two members, one member including a rim and a handle having arms constituting extensions of the rim, said arms being of resilient character and at the rim normally tending to separate, the element being adapted to overlie the rim, and a locking rim with an outline similar to the first mentioned rim only and of rigid character, the locking rim in element locking relation lying immediately below the first mentioned rim and separated therefrom by the element and vertically clamping the element therebetween, and interlocking U-shaped means extending upwardly from the lower rigid locking rim and forming an integral part thereof for upper, element supporting rim engagement for rim locking purposes, said upper rim including outwardly directed means seatable in the U-shaped means when the two rims are in superposed, element locking position.
